Abstract
Alcohol has no effect on the rate of cell division of Urechis eggs except to retard and inhibit. In 2% alcohol the first cell division is inhibited, although the nucleus usually divides. In li''% alcohol the time lapse to first cleavage is increased approximately 15%. In 1% alcohol it is increased approximately 3.5%. Subnarcotizing concns. of alcohol covering the range 1/2% to 1/64% did not stimulate the rate of cell division nor affect it within limits of 1%. It is suggested that the stimulation in the Protozoa, when it occurs, may be largely a nutritive phenomenon. The Urechis egg, with self-contained food supply, presumably avoids this limiting factor.
